Application filed January 6, 1919. Serial No. 269,853.

To all whom it may concern:

Be it known that I, DAVID J. NYsEwANDER, a citizen of the United States,residing at Toledo, in the county of Lucas and State of i0, haveinvented certain new and useful Improvements in Heaters, of which thefollowing is a specification.

The object of this invention is to provide inexpensive means whereby anapartment or building may be efiectively and economically heated. Theinvention seeks to provide an apparatus for the stated purpose whichwill be simple in its construction and compact in the arrangement of itsparts and by which a thorough circulation of heated air will be set upso that all parts ofthe apartment or building will be kept at thedesired temperature.

The invention is illustrated in the accompanying drawings and consistsprimarily in mounting a radiator concentrically within an uprighttubular drum, placing burners within the radiator near its lowerportion, forming a water jacket in the wall of the radiator around saidburners so as to protect the drum from excessive heat by inclosing theburners in a fire chamber, and providing access to said chamber throughopposite doors in the drum and in the wall or" the jacket; and theinvention further consists in certain novel features which will behereinafter first fully described and then more particularly pointed outin the appended claim.

In the said drawin s:

Figure 1 is a vertical section of a heater constructed in accordancewith my invention;

Fig. 2 is an elevation of the same;

3 is a horizontal section on the line 3-3 of Fig. 1.

In carrying out my invention, I employ a cylinder or drum 1 which hasits upper and lower ends open and is preferably construct ed of sheetmetal so that it will be light and inexpensive. This drum is supportedupon. feet 2 so that an open space will be provided between the floor orother fixed support and the lower end of the drum through which cold airmay readily pass into the drum, the air being heated as it rises throughthe drum and escaping through the upper end thereof to circulate throughthe room or building. Housed within the drum and supported in spacedrelation thereto by brackets 3 is an inner casing or radiator consistingof a lower cylinder slightly tapered and the closed as shown. This innerdrum or-radiator will also be preferably constructed of sheet metal andthe lower portion thereof constituting the fire chamber will preferablybe constructed with double walls, as shown at 8, whereby it may beutilized as a water jacket so that water may be heated for domestic useand also for supplementing the hot air circulation as a medium forheating the building or room. IVater may be supplied to this acketthrough any convenient means and I have illustrated portions of a feedor inlet pipe 9 and an outlet or circulating pipe 10 passing through thedrum 1 and having their ends secured in the water jacket so that thedesired circulation of water will be set up. These pipes also serve assupports for the radiator or inner drum so that the same will bemaintained in its proper position relative to the outer drum or casing.Near the lower closed end of the radiator I provide a plurality ofopenings 11, and on the inner side of the radiator I provide an annulardamper 12 which is provided with a similar series of openings 13 adaptedto register with the openings 11 to admit air to the interior of theradiator or to be moved so that the spaces between the said openings 13will cover the openings 11 and thereby cut-off the inflow of ,air. Thisannular damper may be maintained in proper position within the radiatorby any convenient means and I have illustrated overhanging lugs 14secured on the inner surface of the radiator and engaging over the upperedge of the damper, a handle 15 extending through a slot in the radiatorbeing provided for the manipulation of the damper. It will be readilyunderstood that by properly adjusting this damper the inflow of air tothe fire chamber of the radiator may be regulated so that combustionwill be properly supported and a circulation through the radiatorestablished to carry oli obnoxious fumes and gases. To provide for theoutlet of the said fumes and gases, a flue 16 is fitted through theupper portions of the radiator and the drum and has its inner end turnedupwardly within the radiator, as shown at 17 so that the gases and fumeswill be drawn into the flue from the top of the radiator and thencecarried out to the chimney. A check damper 18 may be provided in theflue as will be readily understood. It is intended to employ either gasor oil as the fuel in my heater and for this burner 19 which ispreferably in the form of a ring having jets on its inner periphery,said ring being disposed immediately below the water jacket 8 and beingsupplied through a gas pipe 20 leading through the walls of the drum andthe radiator from any source of. supply; I also provide a vapor burner21 which is disposed preferably at the axial center of the water jacketand may be supported by the gas burner. This vapor.

burner may be of any well-known construction and is fed by a supply pipe22 fitted with a regulating valve 23 and connected to a pipe or tube 24:leading from a supply tank which may be located at any desired point andalso connected with a source of compressed air so that the oil passingto the burner will be in proper condition for rapid and thoroughvaporization. To permit access to the burners for inspection andcleaning of the same as may be needed, I provide a-door 25 in the drumand a similar'door 26 through the jacket of the radiator opposite thefirst door. i

It is thought the operation of the heater will be readily understood.The water pipes 9 and 10 may be connected with a boiler and alsoconnected with a system of radiators and with asource of water supply sothat hot water may be had at such points as may be needed or desired.The water, of course, will fill the jacket 8 and the entire system ofradiators including the circulating pipes and the boiler. Ignition iseffected in the usual manner, the gas burner being preferably lightedfirst and permitted to heat the vapor burner and the latter then beinglighted. from said gas burner. The heat from either or both burners willrise within the fire chamber of the radiator and will play directly onthe water jacket so thatthe drum opposite said jacket'will be to anextent protected. The entire surface of the radiator will be quicklyraised in temperature and will radiate heat. The heat ra diated from theupper portion of the radiator and the outer surface of the water jacketwill act directly upon the air. within the drum so that said air will beraised in tem perature and will flow from the top of the drum into theroom andthrough the building thereby setting up a circulation which.will draw cold air in through the lower end of the drum to be in turnheated and escape through the upper end thereof. The gases and fumesrising from the burner will pass to the top of the radiator and will bethen turned back toward the open upturned end of the escape flue andwill enter said flue and thence pass out through the chimney, the

flow of said gases and fumes being regulated by the manipulation of thecheck valve purpose I provide a gas and set up a circulation through thepipes 9 and 10 toestablish a supply of water'in the boiler and in theradiators connected with said pipes.

The tapered form of the upper portion of the radiator will bring thewalls of the same across the direct path of the ascending heatedcurrents so that they will play directly upon the entire surface andupon the top closed end of the said tapered portion and, consequently, alarge active radiating surface will be utilized so that the aircontained between the radiator and the drum will be very quickly broughtto the desired temperature. The several parts are very simple in theirconstruction and are compactly arranged so that the heater will occupyvery little space and will utilize all the heat generated without anyappreciable waste of the same and consequently a low grade of fuel maybe employed and the cost of maintenance minimized. As the lower end ofthe radiator is closed the inflow of air will be reduced so that thedraft through the radiator will not be strong enough to carry the heatedcurrents rapidly and directly into the flue before they have had time todo the expected work while at the same time sufficient air will beadmitted to maintain the combustion and establish the necessarycirculation. Moreover, should some oil overflow when the initialcombustion is set up in the use of the vapor burner the overflow will becaught by the closed.

lower end of the radiator and thereby prevented from running over thefloor of the room and damaging the same.

Having thus described the what is claimed as new is:

In a heater of the type described, the combination with an upright drumopen at its ends, a door in its wall, a radiator supportedconcentrically within the drum and having a tubular lower portion and atapered upper portion closed at its upper end, a water jacket in thewall of the tubular portion surrounding an internal fire chamber, and adoor through the jacket opposite the other door; of a damper controllingthe admission of air into the lower end of the radiator, an escape flueleading from its upper portion, a vapor burner disposed within and nearthe center of said fire chamber, a gas burner also disposed within said.firechamber at the bottom of the jacket, and means for supplyingappropriate fluid fuel to said burners selectively.

In testimony whereof I afliX my signature.

invention DAVID J. NYSEWANDER. [L. 8.]
